"Thank you all so much for the kind words and for believing in us!" Robertson told fans. "We did too, and tried our best! I really appreciate all the love and support. XO"

Her former fiance also resurfaced on the social networking site to share his thoughts on the split. "A big thanks to you all for your support during this time in my life," the wine maker, 28, said. "It has been a crazy journey over the past couple years and I am blessed to have amazing friends/fam.

The duo got engaged as the cameras rolled, back in November 2011, but were constantly scrutinized by fans of the ABC smash: Robertson was famously catty to the other women on the show, and Flajnik, 29, was caught cheating (with three women!) in exclusive Us Weekly photos.

Indeed, before their split, the duo admitted they were taking a pause before walking down the aisle. "We kind of looked back at some of the other 'Bachelor' relationships that didn't work out and the reason for that is you have so much pressure to move in together and set a date and all this kind of stuff," Flajnik said. "Let's figure out who we are together before we do any of that, and take the pressure off."
